Patented July 11, 1933 UNITED STATESl PATENT OFFICE HERBERT R. BLISS, 0F NIAGARA FALLS, NEW' YOK, ASSIGNOB TO H. B. .BLISS COMPANY, INC., 0F NIAGARA FALLS, NEW YORK, A CORPQRATION 0F NEW YORK ACONEIAINIEIJR. AND REENFORCEMENT THEREFGR Application led January 3l, 1931;v Serial No. 512,527.

rlhis invention relates to the art of fiber board containers, boxes or cartons, such as` contemplates reenforcmg the vertical cor-l ners to prevent the, corners vfrom ripping, breaking, or otherwise becoming ruptured. The particular reenforcement preferably takes the forni of a metallic reenforeement member which may be in the *form of a stitch and the arrangement is such that it preferably may be secured to the fiber board while the same is in blank form permitting, however, the blank to be bent to form a corner during which time the reenforcement is brought into its final recnforciug position.

In the accon'lpanying drawing: Fig. 1 is a perspective viewof one form of container embodying the invention. Fig. 2 -is a plan View of a blank for making the container of Fig. 1. showing the reenforc-v ing devices in position.

Fig. 3 is an enlarged cross sectional view taken substantially on line 3-3 of Fig. 2 showing the association of parts before thev blank is shaped into box form.

Fig. 4 is an enlarged sectional view taken substantially on vline 4 4 of Fig. 1 illustrating the reenforcement after the corner is formed. A

Fig. 5 is a pers ctive view of a different type of box in w ich the invention may be embodied.

Fig. 6 is a plan view of one of the blanks for forming the Fig. 5 box.

Fig. 7 is another view of another one of the blanks for forming the Fig. 5 box, showing the reenforcing device in place.

The container, as shown in Fig. 1, is of the type ordinarily termed a regular slotted container formed of asingle blank, as shown in Fig. 2, creased on the dotted linesl te form four parts 2 which become the four sides ,of the container, and slotted as at 3 to form four wings 4i for th top of the container', and Wings 5 for the bottom. This blank is shaped generally into tubular form and it may be assembled by means of a flap 6 which kis secured to the opposite end of the blank. This may be done by stitches 7. Other means may be provided for securing the ends of the blank together, as for example, the ends may be glued together or a tape may be employed. These variations relate largely to different box structures of which there may be a choice, and the present invention may be utilized in each.

The four lines of creasing form, when the box is assembled, the four vertical corners. The bottom wings 5 are folded to complete the bottom', as is appreciated by those skilled in the art and may be stitched, glued or taped. and of course after the'container is filled the top Wings 4 are folded to seal the top and they may be stitched, glued, or taped.

The reenforcing means for the corners may be utilized in any or all of the corners of the container, Whether verticalA or horizontal, but is especiallyY useful in reenforcing the vertical-corners. As shown in Fig. 1, each vertical corner is reenforced by a'metallic rcenforcing member 10. As shown in Fig. 3, this reenforcement may be in the form of a wire stitch.. These wire stitches may be placed in the fiber board blank while it is as yet in substantially flat form and before it is shaped into the container, and as illustrated in Fig. 2, there is a reenforcement member near each end of each crease which forms a. vertical corner. This permits of easily and rapidly placing the stitches into the flat blanks as they are fed past a stitching machine, so that no extra .handling operations of the formed container are required.

A problemis involved however, in placing the stitches in the flat blank. This comes I :the bight portion preferably is not brought A1li into tight contact with the ber board but is arran d to be sli htly spaced therefrom. This big t portion ridges the crease 1, as' clearly shown in Fig. 3, and the bight portion may advantageously have a conguration which generally conforms'to the ber board blank. Thus it will be noted that the body or bight portion of the stitch has straight side portions 13 with a centrally bowed part 14 which ma correspond in general to the cross sectiona sha of the crease. This particular shaping of t e bod of the stitch is not'entirely necessary an the invention is of such sco e as to cover the stitch whether it is sha to correspond to the blank or not. en the blank is folded along a crease line, the stitch is drawn taut, as shown in Fig. 4. This tautness of the stitch causes itv to effectively embrace the corner to reenforce it against ripping.

, As heretofore mentioned, this reenforcement is especially advantageousI in that environment where the grain of the ber board runs cross wise of the blank, as shown in Fig. 2, thus verticall in the nished container. The vertical sposition of the ain strengthens the box vertically. so that 1t resists crushing action when theboxes are stacked one upon another. It is easier to tear or rip the ber board with the grain than across the grain, and accordingly, the vertical corners are more or less su ject to being ri ped or ruptured with the ain thus dispose These reenforcing s'titc es, therefore, are advantageous in such a box structure. As shown in the drawing, one reenl forcing stitch is used near the top of the The two ends are' provided by vertical corner and one near the bottom. It is within the invention of course to employ as many reenforcing stitches as is desirable, or as many as suits the needs of any particu-v lar container. It will be appreciated that the use of the reenforcement is not limited to containers wherein the grain of the ber board runs vertically nor is the use of the reenforcement limited to the particular box structure as shown.

A different t e of box structure is shown in Fig. 5, this being a three-blank case. The body blank, as shown in Fig. 6, is creased to form a bottom 20, sides 21 and'top win s 22. blan as shown in Fig. 7, creased to form an end wall 23, a bottom flap 24, top flap 25, and side flaps 26. As is appreciated by those skilled in the art, the bottom aps 24 are secured to the bottom blank 20, Jthe top flaps 25 to the top wings 22 and the side aps 26 to the side sealed.

'voi

The-corner reenforcin stitches may betaken i in the end blanks, as s own in Fig. 7, so thatwhen the flaps 26 are bent the stitches'become taut after the manner above described. It-

will also be appreciated that other types of containers may employ the invention;` that any number of rcenforcing stitches may beA 7' l employed at any horizontal as wel reenforced.

Shippin cases are ver for examp e, with cannedI goods and ysonictimes ke t in storage without having been ome of the contents are takenr out at times, and sometimes replaced and this 1particular corner; and that as vertlcal corners may be places severe requirements upon the upper-f parts of the vertlcal corners. The invention `contemplates using the reenforcing stitches merely near the upper parts of the vertical corners. The containers, `such as for cxample, the slotted container shown in Fig. 1,"

is 1n the formof a collapsible tube before final assembly, and is often shipped collapsed, and it has been found that this flattening of the container may be done without materially affecting the reenforcing properties of the stitch.

What is claimed is:

The method of ap lying a metallic U- shaped stitch for reen orcing the corner of a ber board container comprising legs of the U-shaped stitch through a ber board blank while the blank is substantially in at form with the le s penetrating the blank on opposite sides o? a crease line, and with the body of the stitch bridging the crease line and substantially at right angles to the crease line, clinching the legs` of the stitch against the ber board on the side opposite the body of the stitch whereby the end portions of the body of the stitchand the clinched portions of the legs tightly grip the ber board, leaving the center portion only of the body portion of the stitch spaced from the ber board, and then bending the ber board on the crease line to form a corner with the body of the stitch on the outside whereby the centerportion of the bod of the stitch is drawn taut and against the i er board.

In testimony whereof I afx my signature.
